This toolset offers an exporter for Houdini and Javascript loading scripts to be used with THREE.js.
Showcase : http://gratien-vernier.com/houthreeni
More tests will appear in the top-right list as development evolves.
Can be exported and played back in browser :
- Fix count point cloud animated
- Supports PC geometry instancing
- Built-in instancer by attribute (replace CopyToPoint SOP)
- Automatic models export / loading
- Packed Primitives playback
- Automatic fragments optimized export
- Object level (scene) export with transforms animations
- Automatic export
- Runtime sub-frames interpolation
- Allow to reduce payload size (faster client loading time !) and slow motion while keeping smooth animation playback
- HDA can hosts local HTTP server which loads a lightweight HTML / JS setup to test what your exporting in your browser in real time !
Copy the /houdini folder from this repository root in your $HOME or $HSITE, according to your environment pipeline.
Or just reference your local GitHub repository in your houdini.env file.
HOUTHREENI = C:\Path\To\GitHub\houTHREEni\houdini
HOUDINI_PATH = $HOUTHREENI;&
Once installed, simply use the threejs_exporter SOP node.
Consult the attached examples.hip file to learn how to use it with different setups.
To use the JS loader, you'll need to copy these files to your web site / app from the /houdini/scripts/python/houthreeni/host/js folder :
- three.js
Obviously this is THREE.js framework, copy it if you don't use it yet - houthreeni.js
This is the loader for the files generated from houdini - jquery.js
JQuery framework; used to async load JSON file
dat.gui.js and OrbitControls.js are used for the integrated player (UI and camera controls). They are not mandatory but you can get them too if you want these.
You can consult hou.html for an example of integration into a web page.
Improvements Backlog :
- GPU instancing option for PC instances
- Better model loading routine (too much is still assumed)
- Match THREE.js Object3D structure for classes, improve scene management
- Rewing loop mode
- Test and adapt new SOP RBD workflow with packed prims export
- Particle sprites
- Dynamic particles count (birth & death)
- Render options
- Impact web runtime
- Settable from houdini HDA, patches file without full re-export
- Set the way the scene is rendered (materials, PC visibility, ...)
- More scene objects exports (lights)
- Point cloud with primitives (lines, surfaces)
